+++ This bug was initially created as a clone of Bug #64319 +++
Google recently added Google Plus URLs to GTalk users' XMPP vCards. Based on some experimenting with the telepathy-gabble XMPP console, these turn out to be read-only: you can try to set the
<URL> to a different value, and it will claim to succeed, but it has no effect.
With current Gabble, the field just doesn't appear in the Empathy UI (and Empathy crashes, but 3.8.2 will fix that, and I'm backporting that patch to 3.4.x for Debian).
With a Gabble in which Bug #64319 has been fixed, the field will appear in the Empathy UI and be editable. That doesn't seem great either: users will try to edit it and be surprised when they can't. What we want is that it appears, but is insensitive. To tell Empathy to do that, we'll need a Read_Only flag.
Any other XMPP dialects where the vCard is restricted, or where we fake up vCard fields (do we do that on Facebook?), should get the same treatment.
